| Abstract: | In the present paper,the pressure distribution over tool in the forward extrusion of the cylindrical billet and the upsetting-extrusion of the cross forging is calculated by the combined UBM/SM approach suggested in the former paper1]. The obtained results are in good agreement with the experimentally determined results,so then the reliability of UBM/SM method is proved further. |
